Abstract:
We present a new bathymetric compilation of the South Shetland Islands here defined by the following bounding box: 63 to 53.3 W, 63.5 to 60.5 S.
This bathymetry grid was compiled from a variety of multibeam swath bathymetry data acquired during 76 different cruises (see lineage). The data is available as a grid of approximately 100 m resolution in two different formats: a GMT-compatible (2-D) NetCDF and Arc/Info and ArcView ASCII grid format using geographic coordinates on the WGS84 datum.

| Lineage: | The bathymetry map was compiled from a variety of different data sources. The primary data are multibeam swath bathymetry collected from scientific cruises undertaken by British Antarctic Survey (BAS), or acquired during RV Nathaniel B. Palmer, RV Surveyor, RV Maurice Ewing and RRS James Cook expeditions. The complete list of the cruises used for the compilation is described below: James Clark Ross expeditions: JR59, JR69-67, JR71, JR81, JR84, JR93, JR112, JR115, JR149, JR150, JR158, JR179, JR185, JR188, JR193-196, JR194-197, JR228, JR230, JR233, JR239-235-236, JR240, JR244, JR252-254c, JR254D-264-265, JR255A, JR276, JR279-286, JR281, JR299, JR306-307, JR312, JR15003, JR16002, JR16003, JR17003, JR17003A Ewing cruise: EW9101 James Cook cruises: JC055, JC054 NB Palmer cruises: NBP9507, NBP9902, NBP9903, NBP9904, NBP9905, NBP0001, NBP0002, NBP0003, NBP0106, NBP0107, NBP0201, NBP0202, NBP0502, NBP0602A, NBP0603, NBP0606, NBP0703, NBP0710, NBP0805, NBP0908, NBP1001, NBP1003, NBP1103, NBP1105, NBP1107, NBP1203, NBP1304, NBP1602, NBP1603, NBP1608 Surveyor cruises: AMLR95, RITS93A, RITS94B, AMLR90, AMLR92, AMLR94 The grid was created using the mbgrid program from MB-system version 5.5.2336 , using the parameters " -E0.001/0.001/degrees! -G4 -A2 -F1 -R-63/-53.3/-63.50/-60.5" for Arc/Info and ArcView ASCII grid and " -E0.001/0.001/degrees! -G3 -A2 -F1 -R-63/-53.3/-63.50/-60.5" for the netCDF file. This uses a Gaussian weighted mean filter and the bathymetry is gridded as topography (positive upwards) |
